Periventricular-intraventricular hemorrhage (PV-IVH)is one of the most important neurologic lesion of the low birth weight infants. Serial neurosonographic exeaminations were performed in 113 low birth weight infants who were admitted to the neonatal intensive care unit of Presbyterian Medical Center from November 1, 1990to July 31, 1991. The results were summarized as follows: 1) The incidence of PV-IVH in the study was 54% 2) According to Papile's grading system of PV-IVH, grade I was 32.8%, grade II was 45.9%, grade IIIwas 11.5% and grade IV was 9.8%. 3) The onset of PV-IVH was within the first 7 days of life in 82%. 4) Poor activity, apnea, bradycardia and hypotension were statistically significant clinical findings associated with PV-IVH(P<0.05). 5) The risk factors associated with PV-IVH were gestational age, birth weight, hyaling membrane disease, patent ductus arteriosus and artifical ventilation. 6) The mortality of PV-IVH was 0% for grade I, 10.7% for grade II,42.9% for grade III and 83.3% for gradeIV.

The goals of any new cervical cancer chemotherapy should include; a decrease in toxicity, better distant and local control of the disease, prolongation of survival, improvement in the quality of life and palliation of symptoms. The goal of FAC (5-Fluorouracil, Interferon alpha-2a, Carboplatin) neoadjuvant chemothe-raphy is for better surgical therapeutic results in locally advanced and bulky lesions with preo-perative chemotheraphy. This new trend in management of cervical cancer may provide the benefits as follows; reduction of the tumor size, a decrease in numbers of involved lymph nodes, control of microscopically metastatic lesions, improvement of the effects of radiation therapy and providing the chance of operability by lowering the clinical stage than initial prechemotherapy stage. The purpose of this study is to evaluate the effect of FAC neoadjuvant chemotherapy on reducing the size of tumors in cervical cancer. 17 patients in stage I b2, IIa, IIb carcinoma of cervix were treated with FAC regimen; Interferon alpha-2a 6 MIU given subcutaneously on day 1~6, 5-Fluorouracil 750 mg/m(2) given intravenously on day 2~6 and Carboplatin 350 mg/m2 given intravenously on 2nd day. The overall response rate was 58.5%, including 2 complete responses(11.7%) and 8 partial responses(47.1%). Neoadjuvant chemotherapy reduced the mean cervical lesion area from 23.1+9.97 cm(2) to 8.65+5.95 cm(2) in response group. The toxicity was acceptable in this group and the frequent toxicity was myelosuppression. Although limitation of this study are the lack of randomization and the small sample size, FAC neoadjuvant chemotheraphy is a potentially useful modality in the management of patients with locally advanced bulky cervical cancer.

A patient with squamous carcinoma of Bartholin gland including transitional component is reported and the literature related to this disease is reviewed. Carcinoma of the Bartholin gland is rare, comprising less than 1% of female genital tract cancer. This report was summurized a clinical experience of a 53 year old women with Bartholin gland carcinoma, FIGO Stage II. Histologically, this tumor is characterized by poorly differentiated squamous cell carcioma, individually cellular keratinizationa and transitional component. This patient was treated by modified radical vulvectomy with ipsilateral lymph node dissection and neoadjuvant chemotherapy(4 courses) and followed by radiation therapy.

OBJECTIVE: To evaluate the expressions of Ki-67, p53 and p21 waf1/cip1 according to the age and the histologic type of preinvasive and invasive cervical lesions. MATERIAL AND METHOD: Microwave-oven-processed formalin-fixed, paraffin-embedded, cervical biopsy specimens and hysterectomy specimens were obtained from 1997 to 1998 at the Soonchunhyang university Chunan hospital. These included 55 cervical intraepithelial neoplasm(CIN I-III), 14 invasive squamous cell carcinoma and 3 adenocarcinoma, and immunohistochemically evaluated by monoclonal MIB-1 antibody, monoclonal p53 antibody, and monoclonal p21 antibody. Positive index was expressed as a percentage of strong staining cells per 300 counted cells in evenly strong staining area. RESULT: Ki-67, p53 and p21 protein were expressed in the nuclei. Ki-67 was specifically expressed in all phases of cell cycles in proliferating cells. p21 expression was not seen in CIN I and CIN II, but was increased with increasing histologic grade. According to the age, Ki-67 expression was significantly higher in 30 > or =aged group than 30 < or = aged group, but p53 expresson was not significantly different according to age groups, and p21 expression was significantly lower in 50 < or = aged group than 30 > or =aged group. CONCLUSION: Conclusions of this study indicate that cell proliferating rate is higher in young age groups than old age groups. p53 expression was not significantly different according to age and histologic grade. These indicates that mutation of the p53 gene may be associated with the development of cervical cancer, but not associated with the progression of cervical cancer. Besides, p21 expression was increased in increasing histologic grade, but decreased in old aged women. Further study of this paradoxical increase in p21 expression in cervical carcinoma is necessary to clarify the mechanisms of p53 indepent pathway.

Hydrogen peroxide is considered to be a dose- and time-dependent mediator in apoptotic and necrotic death. In this study, we examined the signaling of the E6 and E7 proteins with respect to apoptosis or necrosis after H2O2 injury using an in vitro model with overexpressed E6 or E7 genes. For this purpose, the E6 and E7 gene expressing astrocytes were exposed to 0.01 mM and 0.2 mM H2 O2 solutions. Twenty- four hours after treatment with the lower dosage(0.01 mM H2O2), control, E6-expressing cells suffered about 45% injury and LXSN-expressi ng cells decreased by 67% as assessed by LDH release. However, E7-expressing cells showed less injury, resulting in 20-30% of LDH release. Astrocytes expressing E6, E7, LXSN and mock-infected cells showed a typical apoptotic death patter n on the DNA gel after treatment with a low-dose of H2O2 (0.01 mM), however the y died from necrotic death after a high-dose (0.2 mM) H2O2. Overexpression of HPV-E7 genes protected the cells from apoptotic death after a low-dose of H2O2 and from necrotic death after a high-dose of H2O2, while the overexpression of E 6 genes from the necrotic death. E7 expressing astrocytes showed higher catalas e activity and the levels of E2F protein surged more than 100-folds compared with the control astrocytes. We believe that the activity of E7 protein to protect astrocytes from H2O2 injury was at least partly due to increased catalase, a scavenger protein.

Trisomy 9p syndrome was first described by Rethore, et al in 1970 and about 150 cases have been reported. Trisomy 9p has been reported as either partial or complete. The term "duplication 9p syndrome" instead of "trisomy 9p syndrome" is used since most of the reported patients had only partial duplication rather than the whole arm duplication of 9p. Duplication of 9p syndrome is characterized by growth and developmental retardation, microbrachycephaly, deep and wide set eyes with down-slanting palpebral fissures, "globular" nose, down-turned corners of the mouth, prominent apparently low-set ears, and short fingers and toes with small nails. A 10- month-old male was referred to our department of pediatrics because of hypotonia and delayed development. Karyotype revealed 46, XY, dup(9)(p12p24) by GTC-Banding. We report a case of a duplication 9p syndrome diagnosed by GTC-banding.

A 4-year-old boy showed two episodes of encephalitis/encephalopathy involving disturbed consciousness, convulsion, and paresis associated with the elevated levels of protein and no pleocytosis of the cerebrospinal fluid. MRI studies of the brain revealed symmetrical lesions in the brain stem and thalamus at the first episode, and their sizes were regressed. The lesions were enlarged to the previous size in the second episode. These episodes were not followed by an elevation of the anti-viral antibody titer. In the second episode, intravenous methylprednisolone therapy and intravenous immunoglobulin therapy were introduced.

PURPOSE: The reticuloendothelial system is composed of sinusoidal capillaries, through which even large protein molecules are freely movable between plasma and interstitial space, including the lymphatic system. Therefore, high-dose intravenous immunoglobulin (IVIG) would cause a redistribution of proteins between two compartments. To investigate this hypothesis, we measured plasma protein and lipid levels in patients with Kawasaki disease before and after high-dose IVIG treatment. METHODS: Thirty four children with Kawasaki disease who had complete responses to high-dose IVIG treatment (1 g/kg/day for two consecutive days), were analyzed. Before and after the administration of IVIG, serum analyses were performed for such parameters as total protein, albumin, gamma-globulins (IgG, IgM, IgA), alpha1-, alpha2-, and beta-globulin fractions, and lipid profiles (total cholesterol, HDL-cholesterol, LDL-cholesterol and triglyceride). RESULTS: The levels of gamma-globulins including IgG, IgM, IgA were significantly increased, and IgG was increased by 1,779+/-304 mg/dL after two-dose of IVIG infusion. The levels of albumin, alpha1-, alpha2-, and beta-globulin fractions were significantly decreased by 18 percent, 24 percent, 19 percent and 12 percent, respectively. HDL-cholesterol level was significantly decreased by 20 percent, while LDL-cholesterol and triglyceride levels were significantly increased by 21 percent and 50 percent, respectively. The total cholesterol level was not changed. CONCLUSION: High-dose IVIG treatment decreased the levels of a variety of proteins except immunoglobulins, and the increase of IgG after IVIG treatment was lower than expected. Our results suggest that a part of infused IVIG and plasma proteins, including etiologic proteins for Kawasaki disease, may be distributed to the extravascular compartments. The rapid improvement of symptoms induced by IVIG in Kawasaki disease might be explained by this mode of action of IVIG.

Cerebral palsy (CP) usually arises in the prenatal period, interferes with normal development of the brain and presents as a disorder of motor dysfunction. It is a common cause of severe neurologic disability in children with incidence of 2 per 1000 live births in Canada. Presently, with the persistent increase in premature births and improved care in the perinatal period, the incidence of CP is strikingly augmented. According to neurologically impaired motor ability, they commonly have feeding difficulties, like swallowing, leading to frequent aspiration pneumonia and gastroesophageal reflux. Therefore, improvement of feeding techniques should be an urgent requirement to correct the risk of poor growth. We report a case of CP due to kernicterus who have recurrent pneumonia and growth failure, experience a jejunostomy to overcome the feeding problems.

PURPOSE: Necrotizing pneumonitis is a complication of severe invasive lobar pneumonia characterized by necrotic foci in consolidated areas and its development may be due to excessive host cell-mediated immune response. Necrotizing pneumonitis caused by Mycoplasma pneumoniae (M. pneumoniae) in children and its successful treatment have been reported. We reviewed 5 cases to determine the disease course and outcome in pediatric patients with necrotizing pneumonitis resulting from M. pneumoniae infection. METHODS: Five patients with necrotizing pneumonitis caused by M. pneumoniae who were diagnosed and treated in the Department of Pediatrics, Uijeongbu St. Mary`s Hospital from January 2003 to December 2006 were reviewed in this study. Sex, age, clinical manifestations, laboratory and radiologic findings, treatments, and long-term follow-up outcomes of these patients were analysed retrospectively. RESULTS: One patient was a boy and others were girls. All were less than 5 years of age and had no immunocompromised conditions. Lower pH and glucose, higher protein and LDH were observed in pleural fluid. On the radiologic examinations, all had multilobar pneumonic involvements, especially in the right lobes and lower lobes. Necrotizing pneumonitis was diagnosed on chest CTs taken between two and 20 days following admission. The necrotic foci were identified as multiple low-attenuation changes within the contrast-enhanced consolidation areas mainly in the lower lobes of the affected side of lung. Cavitary necrosis was shown in 3 patients and persisted as pneumatoceles, which disappeared on the follow-up chest radiographs nearly up to 7 months following admission. Macrolide and broad-spectrum antibiotics were administered in all patients and chest tube drainage was performed in 2 patients. Systemic steroid therapy was added in 4 patients. Of those four, 2 patients, both under 2 years of age, improved more rapidly than others in clinical status and radiographic findings. In spite of steroid therapy, one patient died of acute respiratory distress syndrome. Consequently 4 patients were improved and discharged. Two patients who were under 2 ears were normalized and 2 patients who were 4 years of age showed remaining cavitation or fibrosis in the last follow-up chest radiographs. CONCLUSION: Our results may suggest though they are not yet proven nor have they been discussed extensively that younger patients show better prognoses than older children. Further well-designed and large scale studies may be warranted.
